Se hela listan på hindawi.com 2013-06-19 · Anti-IgE antibody (cross-linking) and the bacterial peptide f-Met-Leu-Phe (fMLP) were used as positive controls (for IgE-dependent and -independent activation respectively), and stimulation buffer alone was used as a negative control. Immunoglobulin E (IgE) plays a central role in the allergic response, in which cross-linking of allergen by Fc∊RI-bound IgE triggers mast cell and basophil degranulation and the release of inflammatory mediators. The high-affinity interaction between IgE and Fc∊RI is a long-standing target for therapeutic intervention in allergic disease.

In contrast, monocyte phagocytic function is critically impaired by IgE cross Cross-linking of IgE-receptor complexes by rigid bivalent antigens greater than 200 A in length triggers cellular degranulation. 2012-10-15 Conclusions: IgE cross-linking drives monocyte proinﬂammatory processes and autoregulatory IL-10 in a serum IgE-dependent manner. In contrast, monocyte phagocytic function is critically impaired by IgE cross-linking. Our ﬁndings suggest that IgE cross-linking on monocytes may contribute to allergic disease by both enhancing detrimental inﬂammatory When you have cross-linking of an allergen, it causes a signaling cascade that causes mast cells and basophils to degranulate and release mediators that characterize the allergic response. Classic allergic reactions (type 1) typically get worse over time because the receptors that bind IgE get upregulated, meaning a higher likelihood of allergen-specific IgE binding and crosslinking in the The cross-linking of IgE bound to FceRI on DCs in peripheral blood results in a different response to that seen in LCs in the skin. In blood DCs, this aggregation of IgE-FceRI results in receptor internalization, antigen proteolysis and transport to the MHC class II compartment-like organelle where peptide loading of the MHC class II occurs.

IgE cross-linking triggers many cellular processes that drive allergic disease. While the role of IgE in mediating allergic responses is best described on basophils and mast cells, expression of the high-affinity IgE receptor on other innate immune cells, including monocytes, suggests that it may affect the function of these cells in allergic environments.To determine the effect of IgE cross Results: IgE cross-linking on monocytes increased CD14 expression and induced secretion of TNF-a, IL-6, and autoregulatory IL-10. These effects were greatest in individuals with elevated serum IgE concentrations. In contrast, IgE cross-linking reduced CD64 expression and signiﬁcantly impaired phagocytic function without disrupting the capacity of Cross-linking of the Fc epsilon RI-bound IgE leads to cellular activation, resulting in immediate release of preformed granular components (histamine and tryptase) and subsequent production of lipid mediators (prostaglandins and leukotrienes) and cytokines (interleukin-4 and interleukin-5).
